Device for detecting and destroying drones developed

Increasingly it is possible for electronic hobbyists, especially those living in large cities to get material to assemble a working drone using components available in the market. However there is a danger that these drones may be misused for attacking, especially in high security areas.
The media reported that some government organizations working closely with DRDO had developed a system for detecting and shooting down drones
Exact specifications of the drone killer had not been shared.
However most of the drones are having a limited flying time, of less than 20 minutes, so the drone killer should be activated quickly after the drone is detected, otherwise the drone will disappear.
